ABSTRACT

The objective of this senior project is to protect a three terminal transmission line during fault conditions using the SEL-311L microprocessor based relay and communication assisted permissive over-reaching transfer trip protection. The SEL-311L’s directional distance elements are programmed to trip on internal faults while faults external to the zones of protection are ignored.

Upon sensing a fault condition, the relay issues a trip command to the local breaker and a permissive key for tripping to the remote relay via fiber optic communication. When a permissive key is received and all other permissive conditions have been satisfied, the remote relay issues a trip command to its breaker. Included in this senior project are lab materials for students who wish to complete the lab or for integration into a power protection laboratory in the future. The lab introduces Over-reach concepts and Zone 2 protection. Students gain experience in programming

SEL relays, testing protection functionality, and protective relay logic.

1 INTRODUCTION AND BACKGROUND

Implementation of a Permissive Overreaching Transfer Trip protection (POTT) scheme relies on the application of at least two directional distance (21) units. Distance units require monitoring of both current and voltage to determine the impedance of the connected circuit. During low impedance conditions, the relay is programmed to trip the breaker to prevent over-current conditions from damaging the transmission line and connected equipment. To achieve POTT protection, the directional distance units or relays are connected via a communications channel.

When either relay detects a fault condition internal to the line, a distance element bit is asserted and the relay waits for a permissive trip signal from the opposite relay. In order to receive the trip signal, the other relay must sense the fault condition, issue the trip signal, and send it via the communications channel. Once both of the distance elements have asserted and the permissive trip or key bits have been asserted, the relays close their respective trip contacts. The trip signal is then sent to the trip coil of the breaker causing the breaker to operate and open. Once both breakers have opened, any fault condition that existed in the protected region of the line is now electrically isolated.

1.1

PROJECT DEVELOPMENT

Dr.Shaban originally developed the idea and gave it to me for further development and implementation. The experiment will hopefully be included in the EE444 or a Power Protection laboratory class and executed by students interested in power systems protection and SEL relays.

The project requirements and specifications were developed over a series of conversations with

Dr.Shaban. Upon completion of the lab, students will be able to implement POTT and PUTT impedance protection schemes on a tapped multi-source transmission line using the SEL-311L relays and fiber optic communication. In the future, the power faculty hopes to establish an operational micro-grid with the intent of integrating protection and analyzing system functionality when fault conditions appear at different locations in the system. This project represents one piece of that system. The lab’s delivery date is June 2015, at which time the lab will be fully documented and operational.

7

The transmission line consists of 100mH inductors in series with 10Ω power resistors. The line connects to a tapped load comprised of three wye connected power resistors. System breakers were available and chosen based on past student design. The breaker boxes consist of manual trip/close contacts and a three-pole contactor which simulates the fast operation of a high-voltage circuit breaker. The circuit breaker can be automatically operated by connecting the SEL relay to the appropriate coil contacts. The source(s) are three-phase at 208VLL which is available at all of the lab benches in the power labs.

My knowledge of power protection was minimal at the beginning of this project and required me to rely on the SEL-311L instruction manuals provided by Schweitzer Engineering Laboratories (SEL).

SEL produces thorough documentation for their relays including application notes on advanced configurations such as POTT and PUTT. SEL allows students to enroll in a Computer Based

Training (CBT 101) to gain basic familiarity with their relaying system. The CBT allowed me to understand the fundamentals of communicating and programming the relay. The department was able to purchase CBT 104 which further introduced relay logic programming. Dr. Shaban’s EE518 class notes, and Protective Relaying Principles, and Applications 4th Edition , by J. L. Blackburn, and T. J.

Domin, were heavily utilized as resources for this project [1].

1.2

THEORY OF OPERATION

Distance protection requires measurement of both current and voltage to determine the impedance of a line and connected load at a given time. The impedance for a transmission line network is determined during design phase and is used as a starting point for the design of the distance protection system. The transmission line impedance is a physical quantity that remains generally constant under normal operating conditions. Any impedance detected by the relay lower than 100% of the line impedance indicates a fault condition on that line. The non-directional distance relay zone of protection is represented graphically by Figure 1-1. The diagram consists of a circle centered at zero. The circle’s radius represents the complex impedance value at which the relay will pick up and issue a trip. The non-directional nature of this configuration poses a problem for protection engineers because of limitations it poses for coordination. Regardless of whether the low impedance condition is caused by a fault internal to the line or external to the line, the relay will see a low impedance and pickup. This becomes an issue when designing non radial systems, commonly

8

referred to as loop systems, because the low impedance condition could cause the relay to pick-up and the breaker to open a non-faulted zone. Adding directional capabilities to the relay allows the engineer to design the system so that fault conditions are cleared by the most appropriate protection devices. The appropriate device is that which causes the least amount of system to be disconnected while maintaining system stability. The graphical representation below in figure 1-2 depicts the opening of a non-faulted transmission line.

FIGURE 1-1 NON-DIRECTIONAL R-X DIAGRAM

FIGURE 1-2 RING TOPOLOGY

For loop systems (ring topology) and other non-radial systems, adding a directional unit and communication to the distance relay allows the protection engineer to create zones of protection that do not necessarily extend into other devices areas of protection. Multiple zones with varying impedances and time delay settings can be used to create backup protection for other devices close to the line if necessary. Protection for a line is accomplished with two relays who both look towards opposite ends of the transmission line as shown in figure 1-3. Each relay’s zone of protection

9

overlaps. During internal Zone 2 fault conditions, the relays should detect the fault, issue a trip key command to the relay at the opposite end of the line, and assert its own zone 2 element.

FIGURE 1-3 RELAY ZONES OF PROTECTION

FIGURE 1-4 DIRECTIONAL DISTANCE MHO DIAGRAM

The two most popular schemes for communication assisted distance relaying are POTT and PUTT protection. Permissive Overreaching Transfer Trip requires the distance element (impedance element) to assert as well as receive a trip key command from the relay at the remote end of the line as shown in the logic diagram below. Permissive Under-reaching Transfer Trip scheme is beyone the scope of this project.

CUSTOMER REQUIREMENTS

Two separate meetings with Dr. Shaban early this year identified his needs and requirements. The system’s main objective is to protect a transmission line using the permissive overreaching transfer trip scheme (POTT). Two SEL311-L relays connected via fiber optic communication protect a transmission line fed from two independent sources. At the center of the line, a third terminal is connected which feeds a wye connected load. The sources will both feed the load under normal load conditions. Fault conditions are then introduced into the system at different nodes internal and external to the transmission line system. Single line to ground (SLG), double line to ground (DLG), line to line (LL), and line to line to line (LLL) fault conditions are applied to the system at the locations specified in Figure 3-1. Faults internal to the transmission line will result in a trip while external faults at the load and beyond the transmission line are ignored. The relays detect Zone 2 faults. All Zone 2 trips will require a permissive trip key from each relay to trip the circuit breakers.

The associated lab materials found in the appendix introduce distance relays and basic relay programming concepts to senior level electrical engineering students. The laboratory allows students to gain hands-on experience with the SEL 311-L relay and implement an operational POTT protection scheme.

The requirements and specifications found below in Table 2-1 are based on the customer needs assessment and follow the IEEE1233 standard for requirements development [3]. Marketing requirements were developed through analyzing the ‘Customer Needs Assessment’ (1.2). The requirements analyzed and Engineering Specifications developed satisfy marketing and customer requirements. The engineering specifications developed using the IEEE1233-6.2 ‘Properties of a

Requirement’ (p.12) [3].

BLOCK DIAGRAM LEVEL 0

The level 0 block diagram in Figure 2-1 consists of a single block and describes the basic inputs and outputs from the SEL311-L relay system, breaker, transmission line, and communication system.

The left side of the block diagram describes the inputs and outputs from the West end of the Line and the right side describes the inputs and outputs from the East side of the Line. The left and right sides of the diagram contain both voltage and current inputs from the line. These measurements are used to calculate the perceived impedance of the line to determine if fault conditions are present.

The top of the block represents relay and device power and communication connections. Relay equipment is powered via 120V AC. Breaker control and contactor voltage is 125V DC. The bottom of the block describes inputs and outputs from the relays and breakers to remote annunciator panels typically found in control rooms and on medium voltage switch gear. Figure 2-2 provides a level two-block diagram view of the system and provides more insight into the physical connection of the

The design began with the development of a single line diagram of the system as shown in Figure 3-

1. The single-line diagram identifies the systems main components shows how they are electrically connected.

FIGURE 3-1 SINGLE LINE DIAGRAM

The three terminal transmission line network consists of a line and load tapped at the center of the line. The relays are located at the west and east ends and look towards opposite ends of the line. The relays monitor phase current and voltage. The load consists of three wye connected resistor-inductor pairs. Datasheets and instruction manuals for all the equipment in the system was gathered and the nominal system parameters are tabulated in Table 3-1.

The impedance seen at a relay is affected by the load conditions on the system. Seven possible load flow states were identified and taken into consideration when designing the system. Figure 3-2 identifies the possible states the system can enter under normal operation. Figure 3-2-A (A) was implemented in the lab. Time did not permit for further in-depth study of the effect of load conditions found in Figure 3-2 on system functionality.

20

FIGURE 3-2 LOAD FLOW STATES

21

The design constraints for relay Zone 2 impedance protection require that the relays overreach the line by 120% of the line. Consideration of the load impedance magnitude with respect to each relay and source was taken into consideration in order to prevent overreaching into the load.

Overreaching in to the load could cause false tripping during high load conditions and underreaching the transmission line would result in non-operation during internal faults near the relays.

To prevent non-operation and ensure overlapping Zone 2 protection the relay settings were chosen to be 120% of line impedance. To achieve tripping, the Zone 2 mho circles were overlapped and set to reach 120% of the impedance of the line. Since the load is fed by two sources, the perceived impedance increases because of load sharing. Under normal load conditions, the relays should see an impedance of 200% of the line. If load conditions change and current reverses direction, the relays should block operation further testing would be required to verify operation.

For faults near one of the relays, the effective impedance seen by the remote relay, shown in

Equation 1. Will be one half the impedance of the line in parallel with connected load plus one half of the line. Equation 2 calculates the perceived impedance of the line when a fault condition exists at the remote relay. Equation 3 calculates 120% of the perceived impedance of the line when a fault condition exists at the remote relay.

Z2P represents the diameter of the Zone 2 Mho circle at 75 degrees. Equation 5 and Equation 6 calculate the appropriate diameter for the Mho circle based strictly on the physical impedance of the line. Consideration of the load conditions are not taken into account in these equations. Loads or faults whose impedances fall within the circle and seen by both relays, will operate the Zone 2 elements and trip the breakers.

23

For this project, loading and perceived impedance was taken into account. The settings applied to the relays allow for Zone 2 impedance overlapping based on the calculated Z

FRR

. The SEL-311 maximum reach setting is 64Ω. Without additional equipment to reduce the secondary impedance to the relay, full 120% distance line protection is not possible.

POTT relies on communication between the relays for keying. Only when a relay receives a key signal and sees a fault on the line will the relay trip. In this configuration if communication is lost, the relay will still operate but must wait for the Zone timer to timeout before tripping. Waiting for the timer to timeout increases, the total energy released, and increases the probability of equipment damage and system instability. The timer allows for downstream device coordination and breaker tripping. Figure 3-3 depicts the systems MHO diagram.

CIRCUIT BREAKER

The circuit breakers used in this project were built by Dr. Shaban’s student. The circuit breaker includes automatic and manual trip/close capability. The SEL relay outputs can be wired to the breaker unit allowing remote trip/ close commands to be sent from the relay to operate the breaker automatically. For testing faults at a node, the built-in fault switch can be wired to introduce fault conditions into the test circuit. The line-side fault switch terminals are connected to the three phases of the node and the load side terminals of the fault switch are connected together in the desired fault condition.

SEL-311L

The SEL-311L is a differential current relay used to protect high voltage transmission lines. The relay includes 4 zone phase distance and ground distance capabilities. Differential and other communications assisted protection schemes, including POTT, utilize the relays fiber optic communications channel for data transfer between system IEDs.

4.1.3

LINE IMPEDANCE

Line impedance was achieved using available electrical engineering department resistor & reactor units built by the department’s lab technicians. The unit consists of (2) 10 ohm power resistors rated at 160W and a 100mH 5A reactor all connected in series. Each electrical node is available for use via a banana type connector standoff.

SEL-2924

EIA-232 to Bluetooth serial adapter allows communication between the relay and computer terminal. The adapter is useful when working with RS-232 devices in the field and is a wireless substituted for its wired counterpart. The adapter comes with a USB rechargeable lithium battery.

4.2

CONSTRUCTION

The lab required approximately 6 hours to wire and confirm the connections. Three-quarters of a standard power lab bench was needed to house the required equipment. Connections were made directly to the back of the relays and source using #14 wire and fork terminal connectors. Relay mimic panels are currently being manufactured by students to allow all lab connections to be made with banana to banana type cables and connectors. Once the mimic panels are completed, overall

26

wiring time should be reduced to under one hour. For this system, the same source was connected to each end of the system to model a loop system connection. For integration into the Cal Poly micro grid separate synchronized generation can be applied to the system with similar functionality obtained.

4.3

CONFIGURATION

The relays were programmed with the impedance settings calculated in the design section. Line parameters neglect the effect of the load and treat the line as a continuous line impedance from the local to remote relay terminal. The CT and VT settings were set to 1 because no PTs or VTs were used in the project and no ratio from primary to secondary exists. All voltage and current inputs to the relays are actual system values. Figure 4-1 & 4-2 show the line parameter settings and distance settings entered into the AcSELerator.

27

FIGURE 4-2 PHASE DISTANCE

The following settings (Figures 4-3 - 4-6) represent the trip logic equations, output contacts, and communication settings required to achieve POTT. Figure 4-3 shows the Words when asserted will close the output contacts on the relays. OUT103 when asserted will trip the circuit breaker and is asserted when word !TRIP*!OC are asserted. OUT102 is high when the Close command is asserted.

The breaker requires a momentary close and will remain closed until the trip command has been issued. Although differential protection was not used in this project, the 87 differential settings were left active to allow for utilization of the 87 channel communication via the fiber optic connection.

Special care was taken to ensure that the power resistors were not being overheated by the power dissipated through them. Fault conditions are then applied to the nodes specified on the single line construction drawing located in the appendix. The system is energized and fault switched on momentarily. If the relays are functioning as designed, they should immediately operate and open both breakers, which can be confirmed by the red breaker closed lights transition to two green

34

breaker open lights located on the circuit breaker boxes. In addition, the relays targets displayed on the front panel should light up when a fault condition is sensed. All wiring changes including moving the fault nodes to a different location should be performed with the system de-energized.

5 TESTING

5.1

TEST PROCEDURES

The following are test procedures for verifying the circuit’s electrical and mechanical connections prior to energizing the circuit. Verifying the circuit’s electrical and mechanical connections are imperative to protect both the student and equipment from inadvertent damage.

POINT TO POINT AND MECHANICAL CHECK

The mechanical connections should be checked. With the circuit de-energized, gently pull on the wires and look for wire movement or displacement at the mechanical connection. If the wire connections move, further steps need to be taken to secure the connection. A point to point check using the construction drawings should be done to verify that all connections have been appropriately made. These tests should help eliminate wiring errors and decrease the likely hood a loose or misplaced wire.

WIRING CONTINUITY CHECK

With the load open-circuited and sources de-energized and open-circuited, a continuity / resistance check should be made from the source to the load using a standard multi-meter. All three phases from both sides of the line should be recorded and verified for consistency across all 6 of test points. If any of the test points show a low resistance, resistance difference of 25% or more, or infinite resistance the circuit should not be energized and all connections should be verified. Do not energize the circuit until resistances are equal and approximately 35 ohms from source to load.

35

5.1.1

BREAKER CONTROL VERIFICATION

With the three phase ac source de-energized, energize the DC control voltage and test manual open close breaker functionality prior to energizing the circuit. Verify that the trip and close commands can be issued from the serial terminal within the AcSELerator terminal and that the breaker responds accordingly.

5.1.2

MULTI-SOURCE SYSTEM

If utilizing multiple sources, care must be taken to ensure the systems are synchronized and have proper phasing prior to closing the breaker. Failing to properly synchronize and phase independent sources can result in equipment damage and injury. Procedures for synchronizing and phasing are beyond the scope of this senior project.

36

6 ANALYSIS

Internal line to line faults were selected for analysis because they result in the lowest fault current. By analyzing relay functionality at the lowest fault current magnitude possible, we can deduce that the relay will operate under more extreme fault current conditions.

6.1

INTERNAL LL

FIGURE 6-1 LINE TO LINE FAULT WEST

In Figure 6-1 and Figure 6-2 Phases A & B have been faulted. Figure 6-1 the system is faulted at the

West node as shown on the single line diagram. Figure 6-2 the system is faulted at the Center node

37

as shown on the single line diagram. As seen in the event diagram the fault causes increases in current and decreases in the voltages seen on those phases. The relay word bit M2P picks up indicating that a Zone 2 fault has been detected similarly M1P has not picked up indicating the fault impedance is higher and outside the zone 1 impedance circle. Shortly after the M2P word bit goes high, a permissive key is received shown as the COMM signal and the trip command issued. Both breakers opened successfully.

FIGURE 6-2 LINE TO LINE FAULT CENTER

When fault conditions external to the relays were applied, the relays blocked the trip and did not operate. Blocking trips for faults external to the line allow protection engineers to better coordinate protection and predict system operation after a fault condition has been cleared.

38

7 CONCLUSION

Permissive over-reaching transfer trip protection is a useful way to provide security to vital transmission line infrastructure. By overreaching the transmission line and requiring both relays to sense a fault internal to the line, false trips on faults external to the line become unlikely. The SEL-

311L offers a robust set of protection elements and fiber optic connections for high speed reliable communication between relays. For long distance transmission lines, POTT is a more secure alternative to phase distance and overcurrent alone. The multi-source and tapped load system forced me to think about how system operating and load conditions affect the perceived impedance at the relays. Careful consideration of system conditions need to be part of a protection analysis to avoid false trips and non-operation.

Permissive Over-reaching Transfer Trip Protection (POTT)

Experiment #

Introduction:

Permissive Over-reaching Transfer Trip Protection (POTT) is a communication based protection scheme that relies on phase distance protection elements. Protection of transmission lines in a nonradial systems is difficult to coordinate with other connected transmission lines and distribution because power flow is not static or in one direction all of the time. For the protection of transmission lines, differential protection is not possible because of the losses along the line (I in

≠

I out

). The basic topology of the system consists of a transmission line with a SEL-311L relay at each end connected via a fiber optic communications line. The relays phase distance Zone 2 elements are set to pick-up at 120% of the line. The difference between phase distance and POTT is in the trip logic and communications link. A trip will only be issued if both relays Zone 2 elements pick-up and both of the relays receive a “key” from the other acknowledging that they too could see the Zone 2

Fault. The logic can be better explained by referring to the logic diagram below in Figure 1.

PROCEDURE:

1.

Download and print the construction document set.

2.

Using banana to banana leads, wire the system according to the wiring diagrams in the construction drawing set.

3.

With the power off, test the systems resistance of each phase to the center of the load wye connection. Resistance values should be 20 ohms + (load resistance / impedance) disconnected from the sources for resistance from each phase.

4.

With the power off, verify the resistance between phases at the source is greater than 20 ohms. a.

B to C c.

C to A

5.

Wire Breaker and connect breaker to the SEL relay as shown in the construction drawing set.

6.

Test manual breaker functionality by only energizing the 125VDC and pressing Open/ Close to verify breaker operation.

7.

Program relay using settings found in the appendix of this document.

8.

Upload the settings following the directions found in the appendix.

9.

Based on the Single Line drawing in the construction drawing set. Connect the fault switch to the nodes internal to the transmission line zone of protection.

10.

Apply fault conditions based on the procedure outlined in the “Breaker Operation” section. The fault switch should only be turned on momentarily. The switch should be returned to the off position within 5 seconds of being turned on to prevent equipment overheating and damage.

11.

Apply SLG, LL, LLL faults for internal faults only. Download and view events to AcSELerator
